2 Claims,

This invention relates to a device for use in connection with hot air registers usually built in the wall of a room at or near the outlet of a hot air conductor or duct from a furnace.

One of the prime objects of the invention is to design an inexpensive and efiicient structure to provide necessary and ample moisture in a room which is heated by a hot air furnace, and

also provide means connected therewith for filas it flows from the register.

Another object is to provide a simple, neat appearing attachment which can be easily or quickly mounted or detached to registers already installed, which can be readily filled with liquid for supplying moisture, which requires a minimum of space, and in which the air currents are deflected away from the wall as they rise from the register.

A further object is to provide a device including easily removable dust filters disposed in the path of the rising heat currents, which filters are easily removable and replaceable when necessary to remove for cleaning, repair, or replacement with new filters.

The above and other objects will appear as the specification progresses, reference being had to the accompanying" drawing in which I have shown the preferred embodiment of my invention, and in which like reference numerals indicate like parts throughout the several views thereof.

In the drawing:

Fig. 1 is an enlarged front elevational view of my combination humidifier and air filter.

Fig. 2 is a top plan view thereof with the cover broken away to show the liquid tank.

Fig. 3 is an end elevational view, the broken lines showing the cover swung upwardly to give access to the tank.

Fig. 4 is an enlarged fragmentary edge view showing the manner of mounting the filter strips.

Fig. 5 is an enlarged perspective view of my improved combination humidifier and dust filter,

showing it mounted in position on a conventional hot air register.

Referring now more particularly to the drawing in which I have shown the preferred embodiment of my invention, the numeral 8 indicates a wall 60 in which a hot air register 9 is provided as usual, this register being secured to the wall by means of screws (not shown) or in any other approved manner. sheet metal suitably finished to harmonize with the register and room furnishing and comprises The device is preferably formed of an elongated tank B formed to comprise front, back, and bottom panels Ill, II, and I2 respectively, to which the end members l3 are soldered or welded in the conventional manner, the back panel H projecting a predetermined distance below the bottom of the tank as indicated at I4 and for a purpose to be presently described.

A perforated cover member l5 forms a closure for the-open upper end of the tank and is secured thereto by means of hinges I6 so that the cover may be swung upwardly as clearly shown in broken lines in Fig.3 of the drawing to permit filling of the tank with water, or for cleaning, repairing, or any other purpose.

The front edges of the end members l3 are angled as shown at ll to enhance the appearance and clips 18 are punched in these end wall members in spaced relation, said clips being bent inwardly and thence upwardly to accommodate a short rod or wire section l9 to which one end of a strip of filter cloth 20 is secured, either by sewing or in any other approved manner. A similar rod is provided on the opposite end .of this filter cloth 20, and when these rods are mounted in these clips, this strip spans the distance between the end walls of the device and is disposed directly in the path of the rising heat currents.

There can be as many strips as desired, and these are preferably mounted at an angle with relation to the tank B so that the upwardly flowing air currents will pass therethrough, filtering out dust and other foreign matter carried thereby, said air currents heating the tank so that the liquid contained therein will be evaporated through the perforated cover and. the air in the room properly humidified.

The mounting of the device in position on a register is very simple and easy. It is merely necessary to slightly loosen the screws (not shown) which secure the register 9 to the wall. The depending lip I4 which depends from the tank is then inserted between the wall 8 and the inner edge of the register 9, so that the bottom of the tank rests on the upper edge of said register, after which the securing screws are again tightened and the mounting is completed.

To fill the tank it is merely necessary to swing the cover l5 to gain access to the tank and the dust filters can be easily removed by lifting the rods I9 out of the clips l8 in the end members so that the filter cloth can be removed, cleaned, and replaced as desired.

' The dust filters 20 are preferably mounted at an angle as shown in Fig. 3 so that some of the air currents will be, in a measure, diverted in- NT] OFFICE wardly to more uniformly heat the tank and also to provide for greater filtering efficiency.

From the foregoing description, it will be clearly obvious that I have perfected a very simple, practical, attractive, and inexpensive combination humidifier and air filter for hot air registers and the like.

What I claim is:

1. A combination humidifier and filter comprising a sheet metal tank including end members depending below the bottom of the tank, a lip on the back wall of the tank and adapted to be inserted between a wall and a hot air register for securing the tank in position, a perforated cover hingedly mounted on isaid tank, spaced clips punched in the end members and projecting inwardly and upwardly to form supports, and a flexible filter member having pins on the ends thereof for detachable engagement with said supports so as to secure said filter member in a horizontal and taut position.

2. A combination humidifier and filter comprising a tank including end members adapted to snugly fit the side wall of a hot air register, a perforated cover hingedly connected to and forming a closure for the top of the tank, a lip on the back wall of the tank and adapted to be interposed between the wall and. a hot air register, triangular clips punched in' the end members in spaced relation to the ends extending upwardly to form sharp supports, strips of filter cloth disposed and stretched between said end members and rods secured to said strips and adapted to be detachably mounted on said supports.
